LiHfO2N

LiHfO₂N is an experimental oxynitride ceramic combining lithium, hafnium, oxygen, and nitrogen phases. This material belongs to the class of advanced ceramics under active research for high-temperature and electronic applications, where the incorporation of nitrogen into hafnium oxide lattices aims to enhance mechanical and thermal stability compared to conventional oxides. The material is primarily investigated in academic and laboratory settings for potential use in next-generation thermal barriers, solid-state electrolytes, and high-k dielectric applications where hafnium compounds are already established, though commercial deployment remains limited.
